Worksites, including those that employ multiethnic, low-wage workforces, represent a strategic venue for reaching populations at risk for developing cancer.
We surveyed 197 small manufacturing worksites prior to an effort to recruit their workforces into a randomized clinical trial designed to test the effectiveness of a cancer prevention intervention among multiethnic, low-wage manufacturing workers. This paper assesses the external validity of the trial based on three factors: the percentage of potential trial sites excluded from consideration, the percentage of eligible worksites that adopted the trial, and worksite characteristics associated with adoption.
We found no statistically significant differences between worksites that adopted the trial and worksites that declined the trial with regard to employee demographics, anticipated changes in workforce size, and perceived importance and history of offering health promotion and occupational health and safety activities.
Small manufacturing worksites present a viable venue for reaching multiethnic, low-wage populations with cancer prevention programs, although program adoption rates may be low in this sector. Worksites that adopted the trial are likely to represent worksites deemed eligible for the trial.
工作场所，包括那些雇佣多民族、低薪劳动力的场所，是接触有患癌风险人群的一个战略场所。
在努力招募其劳动力参加一项随机临床试验之前，我们对197个小型制造工作场所进行了调查，该试验旨在测试一项癌症预防干预措施对多民族、低薪制造业工人的有效性。本文基于三个因素评估该试验的外部效度：被排除在考虑范围之外的潜在试验场所的百分比、采用该试验的合格工作场所的百分比，以及与采用相关的工作场所特征。
在员工人口统计学特征、劳动力规模的预期变化以及对提供健康促进和职业健康与安全活动的重要性认知和历史方面，采用该试验的工作场所与拒绝该试验的工作场所之间没有统计学上的显著差异。
小型制造工作场所是为多民族、低薪人群开展癌症预防项目的一个可行场所，尽管该部门的项目采用率可能较低。采用该试验的工作场所可能代表被认为符合试验条件的工作场所。
